[Computerized tomography in post-operative recurrence of bronchial carcinoma].
The authors describe the different types of postoperative carcinoma recurrences, as seen on CT examinations of the chest, in 38 patients who underwent different surgical procedures for bronchogenic carcinoma (12 pneumonectomies, 22 lobectomies, 2 segmentectomies, and 2 atypical resections). The recurrences were classified as follows: 1) recurrence in the bronchial stump; 2) lymph node enlargement; 3) recurrence in the thoracic wall; 4) recurrence in the residual lobe; 5) pleural effusion; 6) nodule in the contralateral lung. The CT findings, correlated with those from plain chest radiographs and clinical symptoms, indicate a higher incidence of recurrences in the hilar region, either in the bronchial stump or as node enlargement. In the discussion, the problems faced after total and subtotal resection are separately analyzed. While after pneumonectomy plain chest radiographs fail to demonstrate the recurrence in most cases, so that CT is nearly always mandatory, after subtotal resection the diagnostic accuracy of conventional radiology appears higher since the residual parenchyma offers good natural contrast. Nevertheless, after subtotal resection, greater difficulties arise at a deeper radiological analysis due to lobar reassessment, the features of which are to be known.
